I started doing that about three years ago. It was a hot and boring summer day here in Texas. At that time I had a short buzz haircut and I had been thinking of trying out something new. I really wanted to drastically change my look for the first time in most of my life. So, one Saturday afternoon, I grabbed an electric hair clipper without a guard and cut it short enough for me to shave it off.
At the end and after cleaning and drying out my dome, I looked in the mirror and touched it. I began to like it almost immediately. The following morning, I took many selfies with different looks and poses including with dark sunglasses.
I was going to only try out for a week, but after that time went by I decided it to keep it after all and let my facial hair grow out more.
I still like it much better than my actual hair. The only haircut that I really liked was the flattop.
